Rhodes city is the largest settlement on the island of Rhodes, boasting a population of around 90,000 inhabitants. Along with many Gothic buildings in the historic upper city area of Rhodes, the city has a beautiful modern harbour and an array of tourist accommodations. Driving a private car rental is the best way to explore the city and the island's surrounding areas. Enterprise Rent-A-Car has several car hire locations in Rhodes, including a branch in Ialyssos, a convenient airport branch, and another location on the southern end of the island, near Lardos and Lindos. Rhodes is famous for its mediaeval fortifications that were built during the Crusades by the Knights Hospitaller. Partially due to the long-lasting construction efforts, the old town of Rhodes was named a UNESCO World Heritage Site in 1988. Along with Ottoman and 20-century Italian architecture located throughout the city, Rhodes has plenty of sights to offer holidaymakers.
